Why Buyers Reorder

Same Icon.
Higher Ground.

We built C11 around the two things B2B buyers actually get burned on: fabric that dies after ten washes, and colour that shifts between reorders. Both are covered in writing.

  1. 01

    Fabric & Colour Warranty

    Written coverage on colourfastness, pilling and seam integrity. A failed batch is remade — you don't argue about it.

  2. 02

    Factory-Direct Rates

    No trading-house markup between your PO and the cutting table. Premium knits at prices that leave your programme a margin.

  3. 03

    Everything Under One Roof

    Uniforms, tracksuits, socks, sleeves, bags and helmets from one supplier — one invoice, one lead time, one contact.

  4. 04

    Built For Repeat Orders

    Patterns, grading, Pantone references and roster names stay on file. Season two is a reorder, not a new project.

Who Reorder.

We sent a photo of last season’s jersey and had a mockup back the next morning. The sample matched our Pantones on the first pass — that never happens.

Before You Ask

Questions Buyers Always Ask Us.

What is your minimum order quantity?

From 25 pieces per style for custom uniforms and tracksuits. Private label programmes and accessories carry their own MOQs — both confirmed on your quote.

How long does production take?

Mockups in 24 hours. Sampling and bulk timelines depend on product, quantity, fabric and decoration, and are confirmed on your quote. Tell us the date you need kit on bodies.

What does the warranty cover?

Colourfastness against washing and sunlight, pilling resistance, and seam integrity for the stated period. A failed batch is remade at our cost, in writing.

Do you manufacture private label?

Yes — your labels, tags, packaging and blocks, produced under NDA. Many brand clients start with one style and grow into full seasonal ranges.

Can you match our existing kit?

Send a garment from your current supplier. We reverse-engineer the pattern, match the Pantones and quote like-for-like — usually a better hand-feel at a lower rate.

Who handles duties and delivery?

We quote DDP to the US, UK and EU, so the number you approve is the number you pay. DAP and freight-collect are available too.
